Question

Solve the literal equation for x

Answer 1

Answer:

see explanation

Step-by-step explanation:

(1)

y = 5x - 7x , that is

y = - 2x ( divide both sides by - 2 )

x = - $\frac{1}{2}$ y

(2)

mx - r = y ( add r to both sides )

mx = y + r ( divide both sides by m )

x = $\frac{y+r}{m}$

(3)

2x + 3y = 10 ( subtract 2x from both sides )

3y = 10 - 2x ( divide both sides by 3 )

y = $\frac{10-2x}{3}$

(4)

5x - 3y = 4 ( subtract 5x from both sides )

- 3y = 4 - 5x ( divide both sides by - 3 )

y = $\frac{4-5x}{-3}$ ( multiply numerator/ denominator by - 1 , to 'tidy up' )

y = $\frac{5x-4}{3}$
